A venturi tube is a measurement device that uses the pressure differential between two sections that differ in diameter. Using Bernoulli’s principle, the velocity and flow rate can be approximated from the pressure differential measured across the two areas within the venturi tube. The venturi tube is a popular method of calculated volumetric flow rates for gases, water and oils, and other internally flowing fluids. The venturi tube given here is designed specifically for use with 80mm DC fans. The venturi tube has been used to verify fluid dynamics theory while also characterizing the relationship between duty cycle and flow rate of the fan. The fan included in this kit has been characterized to output approximately 75 cubic feet per minute (CFM).
